A rubbish script, terrible acting from all concerned -- including, I regret to say, Uma Thurman -- and Woo's action histrionics uneasily confined to science lab interiors, all conspire to produce a movie of utter redundancy.

This movie just sags, even in the action scenes.

Some remedial script work is in need, and the characters are far from compelling. But the action is up to scratch and it rattles happily along.

It feels more made-for-video than big budget and, though the picture narrowly escapes being a complete failure, you expect so much more from everyone involved.
